March 3 Claims.

The present invention relates to motor-cultivators of the kind which have a two-wheeled motor unit, a trailing working tool, and a trailing wheeled seat portion for the operator, its object being to provide an improved construction wherein the operator can steer the motor unit and raise and lower the working tool more readily than hitherto been possible.

According to the present invention, the improved motor cultivator comprises a wheeled motor unit, a working tool pivoted thereto for horizontal movement about a vertical axis, steering means pivoted to said motor unit for horizontal movement about a vertical axis independently of the working tool, and a trailing wheeled seat portion pivoted to the steering means for vertical movement about a horizontal axis which extends transversely of the vehicle.

In the accompanying drawings, which are above all schematic and are given by way of non-- limiting example of one of the forms of construction of the invention:

Figure 1 is a vertical apparatus.

Figure 2 is a corresponding plan.

The wheeled motor unit I comprises a horizontal shaft 2 on which the driving wheels are carried at each side.

At the rear of the motor unit is provided a pivot shaft having an upper vertical shaft 3 and lower vertical shaft 4, and carried on a central boss 5.

The lower shaft 4 supports a pivotal arm 8 bearing a working tool and coupled by a ring 9. A shackle it has two arms which pivot respectively on the upper shaft 3 and lower shaft i.

The upper part i I of the shackle I U is extended by a sleeve I2 receiving a rotatable steering column it having at its forward extremity a I l engaged with a toothed sector I5 keyed on the upper vertical shaft 3, and serving for steering the motor unit.

The shackle It also carries a horizontal pivot I6 on which is engaged a bar I? which extends rearwardly as a horizontal rod I8 having at its sectional view of the the other and carrying at the lower end a seat mounting comprising a horizontal pin 29 receiving a rotatable horizontal sleeve 2| fast to a seat 22 and to a control lever 23, the relative rotary position of which with respect to the pin is limited and secured by engagement with a toothed sector 24 on the portion I9.

A rear Wheel 25 carrying the seat mounting is pplication France connected to a vertical shaft 25a which can freely turn in the bush 26 of the support Eta and can be secured against rotation by a stop detent 21.

The operation is as follows: With the shaft 25a secured against movement the driver seated on the A, B to the right or left, without the rod I8 leaving the axis X, Y.

When it is desired, on the contrary,

20 by movement of the direction of the arrows portion pivoted to the steering means for vertical movement about a horizontal axis which extends transversely of the vehicle.

2. A motor cultivator comprising a motor unit, a driving wheel mounted at each side thereof, a vertical pivot shaft mounted on said motor unit and having upper and lower halves, a Workcoup-led to the lower half of arm shackle coupled pivotally on the upper and lower parts of the pivot shaft for horizontal engaged with said bevel gear wheel for steering the motor unit, a rearwardlyextending horizontal rod pivoted to the shackle for vertical movement about an axis extending transversely of the shackle, a seat mounting connected to the rear end of said rod, and a rear wheel carrying said seat mounting.

3. A motor cultivator comprising a wheeled motor unit, a working tool pivoted thereto for horizontal movement about a vertical axis, steering means pivoted to said motor unit for horizontal movement about a vertical axis independently of the working tool, a rearwardly-extending horizontal rod pivoted to the steering means for vertical movement about a horizontal axis extending transversely of the steering means, a telescopic vertically-depending portion at the rear end of said rod, a horizontal pin at the lower extremity of said telescopic portion, a sleeve rotatably carried on said pin, means for securing the relative rotary positions of the pin and sleeve, a seat support secured to the sleeve, a vertical shaft journalled in said seat mounting, and a rear wheel connected to said vertical shaft and serving to carry the seat mounting.
